Three types. The ways to obtain patent rights are: 1. Original acquisition, which can also be said to be independent research and development. 2. Patent transfer: transfer the patent right directly to the counterparty and charge a transfer fee. Note: Sign the contract, and then go through the formalities for changing the bibliographic items with the State Intellectual Property Office. 3. Patent implementation license and charging of patent fees. Article 42 of the Patent Law states that the term of invention patent rights is twenty years, and the term of utility model patent rights and design patent rights is ten years, both calculated from the date of application.
